I just bought a profile BOA stem for the singlespeed:

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

The description says the handlebar clamp diameter is 25.4mm, which matches my handlebars. The directions that came with the stem say they are for a "H2O threadless stem" which doesn't seem to match the product I bought??

The thing that threw me most was this statement in the directions "Do not use mountain bike handlebars with a diameter of 25.4mm as they will NOT fit properly in this stem." I'm using 25.4mm road handlebars, and installed them into the stem, with no apparent issues (they're just not torqued down yet). A check of the same product on profile's website says the clamp diameter is 25.4mm:

Seems like they just sent the wrong directions, no? Any possible concerns here?
